Floor strands-agents at 1.48.0, where the Storage interface landed - #19
Merged

Conversation
pyproject declared a bare strands-agents dependency, so pip could resolve any SDK version, including ones predating the unified Storage interface this package implements. The failure would then be an ImportError at first use instead of a clean resolver error at install time. The TypeScript package has carried the equivalent floor (@strands-agents/sdk >=1.10.0) since the import. The floor is measured, not guessed. The interface landed upstream in strands-agents/harness-sdk #3259 (commit 1aff2707); comparing that commit against release tags shows python/v1.47.0 predates it and python/v1.48.0 is the first release containing it. Verified empirically both directions: the full unit suite passes on a venv pinned to 1.48.0 (53 passed), and on 1.47.0 the package fails exactly as an unfloored install would, ImportError: cannot import name 'StorageError' from 'strands.types.exceptions'.
